"Everyone's been so nice, whether they know me as Dr. Horrible or Barney Stinson or Doogie Howser. People have been very kind and respectful of the fact that I have a life that's outside of the business, but also relatively interested in what goes on in that life," Harris explained to Parade.

"I think Twitter helps. Twitter is fun because it allows a kind of intimacy with people who want to follow you. You can toss them a funny joke or picture or story that's unique to you and doesn't come through the publicists and the studios."
